In “What Becomes of the Broken-Hearted,” When dealing with matters of the heart, people react in many different ways: Still crushed over her break-up, Spencer (Troian Bellisario) continues her downward spiral as she now takes her anger and hurt out on Mona (Janel Parrish). Caleb (Tyler Blackburn), on the other hand, hides his pain by being closed off when discussing his father.

But when Hanna (Benson) devises a plan to bring father and son back together, will that help Caleb heal old wounds or just make things harder? And Aria (Hale), who is still missing Ezra (Ian Harding), finds she is spending more time with Wes (Gregg Sulkin).

Meanwhile, Emily (Mitchell) and Jason (Drew Van Acker) work together to put together the pieces of Ali’s (Sasha Pieterse) trip to Cape May and what really happened during that vacation.
